FREDERICK JOIIN HARBRIDGE, OF GRAVENHURST, CANADA.

PRlNTlNG-PRESS.

SPECIFICATION forming part of Letters Patent No. 622,427, dated April 4, 1899.

Application filed September 30, 1897. Serial No. 653,612. (No model.)

To all whom it may 00.7b067'7bf Be it known that I, FREDERICK JOHN HAR- BRIDGE, printer, of the town of Gravenhurst, in the district of Muskoka, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Printing Presses, of which the following is a specification.

My invention relates to improvements in printing-presses; and the object of the invention is to design a simple, cheap, and easy-running foot or power press which may be run at a much greaterspeed than the ordinary presses now commonly in'use and be limited only by the quickness with which the sheets may be fed; and it consists of the construction hereinafter set forth, and particularly pointed out in the claims.

Figure 1 is a general perspective view of a printing-press constructed according to my invention. Fig. 2 is a longitudinal section through. the press, looking from the opposite side to that shown in Fig. 1. Fig. 3 is an enlarged sectional view showing the cylinder and the parts coacting therewith. Fig. 4 is a detail of the clamp for holding one edge of the paper to the cylinder. Fig. 5 is a detail of the cam and collar. Fig. 6is a detail view.

In the drawings like letters and numerals of reference indicate corresponding parts in each figure.

A is the frame of the machine, which is preferably rectangular in form.

B is the main driving-shaft, which is suitably journaled in bearings secured to the intermediate bars A.

B is a pinion secured in the end of the main shaft B and meshing with the gear-wheel O, secured on the counter-shaft G. A

D is the cylinder, the end spindles d of which are journaled in the bearing-standards E E, slidably supported upon the tongue side bars F F of the machine.

D is a pinion which is secured to one of the end spindles of the cylinder and meshes with a rack G, located to the inside of one of the tongue side bars F.

H is the bed-plate for the chase, which is suppo7rted on the eccentrically-journaled rollers z 2-.

pending as shown.

' municated to the chase bed-plate H.

I is a forked connecting-rod pivotally connected to the lower end of one arm and having the other end pivotally secured in the fork J, which is pivotally connected to the front arm H.

K is a lever pivoted in the frame of the machine and provided with lugs k at the upper end thereof, between which is secured the bracket is.

L is a screw-spindle provided at one end with a right-hand thread and at the other with a left-hand thread and at the center with the hand wheel 1. The screw-spindle extends at one end through the bracket and at the other end into the fork J. At each end the spindle L is provided with suitable nuts, and by loosening them and adjusting the spindle the position of the eccentrics It may be adj usted.

M is a cam secured to the shaft 0. The cam M is designed to impart a rockingmov e ment to the lever K, so as to raise and lower the chase bed-plate H. The adjustment of the screw-spindle L serves to limit the amount of upward throw the cam M will impart to the chase bed-plate H. The collar of the cam M is provided with a groove m, into which fits a pin m, attached to a lever M, which is pivoted on the rod m extending into the frame of the machine, as indicated. By tilting the lever m laterally the cam may be thrown to one side of the lever K, which is of a limited width, and thereby no upward motion is com- This is necessary should the operator neglect or misfeed a sheet into the machine, as otherwise the type would print on the cylinder.

' Nisa delivery-table provided with suitable inclined sides 17. and high back n and open rear end. The delivery-table is supported on the shaft 0 and front roller h.

0 are supplemental horizontal side bars at the upper front end of the machine, such side bars being supported on the main frame by the uprights O.

P is a feeding-table pivoted on the rod 19, extending between the side bars 0.

P is a flap hinged, as indicated, at the feeding end of the table P next the stop-fingers. The flap is normally held up by the tension of a fiat spring P. P is a projecting plate located, preferably, at one side of the flap P,

ICO

at the outer edge thereof. One side of the feed-table is provided with a hanger p, having journaled in the bottom end thereof the roller 12*.

Q is a side bar provided with a raised portion q, an inclined portion q, and a low portion which is connected by a pin (1 to the bearing-standard E.

Although I show only one roller and side bar Q, it will of course be understood that there is preferably one provided at the opposite side of the machine, which is of course not shown.

R are stop-fingers which are secured on the rod 0', which is held in bearings r, secured to the top of the feeding-table P.

S is a spindle journaled at each end in the curved rear end of the side bars 0. The spindle has secured to it-a plurality of grooved wheels T, in which are fastened tapes! of cotton or any other suitable material. I preferably use three wheels, and the ends of the tapes are fastened and wound around the grooves when the cylinder is in its normal position, the other ends of the tapes being fastened around the rod U, upon which the areshaped gripping-fingers u are secured.

3 is a clamping-bar, which is provided with end notches 4 and spring-fingers 5, extending over such notches, the tape being designed to be passed through the notches and up over the spring-fingers, so as to hold the clampingbar 3 in any desired position on the tapes. A central tape 25 may be also provided where the sheets of paper are of unusual length, the ends of this tape being looped over a fiat springfi11ger 6, secured to the clamping-bar.

The rod U and gripping-fingers are held in a recess (1 in the cylinder D, the rod U extending through the ends of the cylinder and being journaled therein. Thegripping-fingcrs when closed, as indicated in the drawings, form an arc of the circle of the cylinder and are of any desired number, extending across through the recesses (1. These gripping-fingers u are held to the rod U by setscrews 20, extending through the hubs of the fingers, and the combined finger-s on the red are spring-held in the recess by the spring ta which is fastened to a pin a in the center and has the ends passing to the outside of the setscrew it toward each end, as indicated in Figs. 1 and 3.

V is a bar secured to one of the side bars 0 and provided at the rear end, near the cylinder, with two guiding-ribs separated from each other-viz., c and 1)". One end of the rod U is bent into the form of a crank-arm U (see full lines, Fig. 1, and dotted lines, Fig. 3) and is designed to coact with the ribs 1) and r, for a purpose which will hereinafter appear.

6 is a cross-rod which is secured on the end of the arms e',which are pivotally but stiffly held in the ends of the arms 6 attached to or forming part of the bearing-standards E.

E are spring-fingers provided with curved ends, which are secured in the clamps E secured to the cross-rod 6. These spring-fingers are designed to be brought down against the paper as it passes onto the cylinder by the arm E having bent end e, which engages with the L- shaped projection E as the cylinder is being caused to move toward the feeding-table. As the pivotal connectionbetween the arms 6' and e is a rigid one, held so by jam-nuts on the end of the pivots which connect said arms, which bind against the arms 6 it will be seen that the spring-fingers as the cylinder recedes will maintain the same position to which they are set, which will be close upon the cylinder, and will thus serve to keep smooth the sheet of paper which is being fed onto such cylinder.

WVhen the cylinder reaches the limit of its rearward movement, the bent end of the arm E comes in contact with the inclined projection e and thereby tilts the arms (2, and c011- sequently throws the rod and the fingers away from the cylinder, so that as the cylinder is returning to normal position the fingers E do not come in contact with the now-printed matter on the cylinder, which should they do would have a tendency to smudge it.

Having now described the principal parts involved in my invention, I shall briefly describe the feeding and the printing of the paper.

The paper is fed in sheets upon the table B and pressed against the stop-fingers R. At the period the sheet comes againstthe stopfingers the pitman 2, connected to the gearwheel 0 and the bearing-standards, is so timed and arranged that the cylinder starts to move from the position shown in full lines in the drawings to that indicated by dotted lines at the left, (see Fig. 2,) when the roller 19 will roll down the incline q of the bar Q and thereby serve to bring the table andthe sheet of paper beneath the stop-fingers into close proximity with the cylinder. At this moment the gripping-fingers of the cylinder, moving in the direction indicated by arrow, Fig. 2, are caused to open by the end of the crank-arm traveling up the outer rib '0 of the bar V, such fingers then serving as the cylinder rotates in the direction indicated by arrow to grip the sheet off the end of the flap P. After the end of the crank-arm U has traversed the front rib i), so as to open the grippers, the plate P of the flap P will have arrived underneath one of the end grippers and will then momentarily serve to hold down the flap P while the edge of the paper is passing underneath the stop-fingers. \Vhen this particular gripper has passed the plate, the rib 11' serves to allow the arm to come down gradually, and thereby close the gripping-fingers gradually upon the paper without any danger of cutting it. The paper now being grasped by the gripping-fingers, the cylinder is caused to rotate in the opposite direction to that indicated by arrow, Fig. 2, and pass with its bearing-standards rearwardly on the machine, the pinion D meshing with the rack G and serving to prevent any slipping of the cylinder. The paper as it passes around the cylinder is smoothed over by the spring-fingers U and the tapes tpass from off the grooved wheels T, as indicated by dotted lines in Fig. 2, until the clampingbar 3 passes onto the opposite edge of the paper. During this rearward and rotary movement of the cylinder and the paper around it the type on the chase is brought up and held by the cam M, so that the impression is transferred to the sheet. When the cylinder has reached the limit of its rearward movement,

' the arm E rises on the inclined block E and then relieves the spring-fingers E from contact with the now printed paper on the cylinder. Upon the cylinder returning to its former position the arm U rises upon the guiding-ribs o and causes the gripping-fingers to release this edge of the paper,which drops onto the delivery-table N, and as the tapes t are rewound upon the wheels T the clam ping-bar 3 releases the other edge of the paper.

It will of course be understood that the clamping-bar is situated at the proper distance along the tape from the gripping-fingers to grasp the other edge of the paper of whatever width may be used.

To rewind the wheels after the tape has been drawn out from them by the rearward movement of the cylinder, I provide,as shown, a helical spring 7, which is secured at one end to the end of the spindle S and at the other end to the bearing of such spindle, as indicated in Fig. 1. This spring winds up as the tapes are being withdrawn and of course exercises arwinding movement upon the tapes as the cylinder is being restored to its normal position.

Among the advantages arising from the use of my machine it will be apparent that the feed is necessarily much quicker than in the ordinary press, Where the feeding and the delivery of the sheet have to be accomplished upon the same table, that the feeding of the sheet is very simple and positive, and that the. affixing of the sheet to the cylinder is also very secure, so that there will be no slipping during the time that the sheet is beingprinted. It will also beseen that very effectual means are provided, whereby if a sheet is not fed the cylinder is not spoiled or defaced by being printed upon.
